Quote Hi everyone,

I'm hoping some one can enlighten me on this issue, and let me know if it's an issue at all or if i'm just over thinking this process.

I have a finsished product, and on the time line if I right click on my clip and bring up the project details under "view properties" under "video" the frame rate is shown as 29.97, which is fine, BUT, when I go to produce the video (to put on a DVD), I either have to go with the default MP2 settings which are uneditable, or if I try to make a custom profile which I did with better bitrate, I have no way of changing the frame rate. It shows up as 23.98. Should these frame rates match, and if so, how am I able to perform that task. Or does it matter at all. Will if affect the finished product. (Which is by the way a dance performance, fast movement, changing lights, etc.)

Thank you for any help you can give.

Assume by DVD you really mean DVD and not BD or AVCHD. You don't really need to "Produce" the video to put on DVD, you can just use the "Create Disc" module and the source will be converted to standard format for DVD. The MPEG-2 DVD HQ setting in "Produce" is very near the highest bitrate you can use for a standard DVD with PD. If your source is 29.97, common for NTSC video on media, you don't want to convert that to 23.976 fps, it will look choppy.

Hi Jeff, and thanks in advance for your assistance. Yes, I really mean DVD, not BD or AVCHD. So I can bypass that produce section all together, and just go direct to create disk? I have always gone to the produce step and selected MP2 on every DVD project I have done haha...what a waste of time huh? I thought I had too go through that step.

Ok, so, if I go to create disk...On the Video and Audio Settings section, the video encoding is Mpeg-2 and the HQ 720x480/60i (9.5 mbps) is the only selection. Is 60i changing everything to the worse? I have a progressive clip, is the i interlaced? And is the 60 the frame rate? I'm kind of confused now. I thought it was best to create a disk with the same settings as the project for best outcome quality-wise, especially the frame rate. I know for a DVD I HAVE to go with the 720x480, but the frame rate is what has me puzzled. I know 29.97 is basically 30, so is 60i equivelent to 30 in some manner due to the interlacing?? My head is going to go kaboom!

Yes, a waste of time. It does nothing the alter or change what needs to be done in the "Create Disc" module with the timeline contents. The only exception is if you start a new project and then use that "Produced" video in the timeline and reset chapters and such and then go to "Create Disc". If this is done, one needs to make sure that you "Produce" to a DVD compliant format or you will simply encode the video yet again during "Create disc" which can lead to additional quality issues.

60i wording because it is an 'interlaced' format. Basically this describes a recording mode where 60 fields (not frames) per second are recorded. Two fields make up on full frame, and the term field means that either the odd or even numbered lines of an image frame are recorded. The 60i format was developed for the NTSC color TV system standard of 1953. Since 60i is fields, that standard defines an effective 29.97 interlaced frames per second for NTSC Color TV.

Because DVD has to meet the standard above, your progressive clip, or any non compliant timeline footage, will be converted to interlaced during the "Create Disc" encode process.

Jeff, thank you for your time, expertise, and very thorough explanation of this. I appreciate your help. You very clearly explained a lot and saved my brain from much confusion.
